A charge of Q coulomb passes through any cross-section of the conductor is given by `Q = 3t^2 - 2t + 10` where Q is in coloumb and t in second. Find the current flowing through the conductor at the time instant , t = 2 seconds.

The amount of charge passing through any section of a conductor as a function of time is given by : Q = 5t^3 + 3t^2 + 2t + 7 calculate the current flowing through the conductor at the end of 1 second. Assume charge in coulmb and time in second.

The charge (Q) flowing through a conductor at a given instant of time (t) is given by Q = (2t^2 - 3t) coul. Then the current at time instant t = 2 second in ampere is
